Re: HOTPOINT WDL 520 not drying properly
11 should be the hottest as its the cottons one, i wouldnt say which was hottest to her, as my experience of customers, if they get wind your trying to work out if they are at fault, then they will lie to save face, rather than be honest and accept its their fault.
other option is to go there as a last call of the day, make sure she has tea and biccys and put a wet couple of towels in, spin them at full speed, then set it to sensor dry dryest setting and chill there. ive had to do that with one customer, would have been utterly dull if it wasnt for sky sports and a 40-something inch plasma he fortunately wanted to show off 🙂
